Many wish they could bring Tupac back from the dead. Well, now you can, sort of! And we're not talking about his hologram, either. There's an app for that. It's called "Me" -- which uses 3D technology and artificial intelligence so you can keep your loved ones forever on your smartphone.

It's said to recreate their personality and image to help you move on. First, you create a 3D scan of the person you want to trap inside your phone, and then you upload the scan and wait for them to die.
